Description

ストラドルドビークルStraddle vehicle
　本発明は、鞍乗型車両に関する。 The present invention relates to a saddle-mounted vehicle.
　特許文献１には、フレーム本体にエンジンとギアケースを含むエンジンユニットを固定した鞍乗型車両が記載されている。特許文献１の鞍乗型車両は、フレーム本体にエンジンユニットを固定してフレーム構造体を構成し、エンジンユニットをフレーム本体の剛性メンバーとして使用している。 Patent Document 1 describes a saddle-mounted vehicle in which an engine unit including an engine and a gear case is fixed to a frame body. In the saddle-mounted vehicle of Patent Document 1, an engine unit is fixed to a frame body to form a frame structure, and the engine unit is used as a rigid member of the frame body.
特許第３９９２７９８号公報Japanese Patent No. 3992798
　特許文献１の鞍乗型車両は、エンジンユニットをフレーム本体の剛性メンバーとして使用する。これにより、フレーム構造体全体の剛性を高めている。しかし、特許文献１に記載の鞍乗型車両は、エンジンユニットがフレーム本体に固定されている。そのため、エンジンからの振動がフレーム本体を介して鞍乗型車両全体に伝わってしまう。 The saddle-mounted vehicle of Patent Document 1 uses the engine unit as a rigid member of the frame body. As a result, the rigidity of the entire frame structure is increased. However, in the saddle-mounted vehicle described in Patent Document 1, the engine unit is fixed to the frame body. Therefore, the vibration from the engine is transmitted to the entire saddle-type vehicle via the frame body.
　エンジンを搭載する鞍乗型車両においては、入力に対する高い応答性を実現しながら、エンジンユニットからフレーム本体に伝わる振動を抑制することが求められる。 In a saddle-mounted vehicle equipped with an engine, it is required to suppress vibration transmitted from the engine unit to the frame body while achieving high responsiveness to input.
　本発明の目的は、入力に対する高い応答性を有しつつ、エンジンからフレーム本体に伝わる振動を抑制する鞍乗型車両を提供することである。 An object of the present invention is to provide a saddle-type vehicle that suppresses vibration transmitted from an engine to a frame body while having high responsiveness to an input.
　本発明者らは、鞍乗型車両において、エンジンユニットからフレーム本体に伝わる振動を抑制することについて詳細に検討した。この結果、本発明者らは、次のことが分かった。 The present inventors have studied in detail about suppressing vibration transmitted from the engine unit to the frame body in a saddle-mounted vehicle. As a result, the present inventors have found the following.
　鞍乗型車両のフレーム本体の剛性を高めるために、例えば、エンジンユニットの一部を使用することが考えられる。例えば、サイドチューブとピボットチューブにより構成されたダイヤモンド型のフレーム本体にエンジンユニットを取付ける。この時、ダイヤモンド型のフレーム本体のサイドチューブに、エンジンの上部を弾性マウントにより取付ける。また、ダイヤモンド型のフレーム本体のピボットチューブにエンジンユニットの後部をリジッドマウントにより固定する。
　このように鞍乗型車両のダイヤモンド型のフレーム本体にエンジンユニットを取付けることにより、鞍乗型車両のフレーム本体の剛性を高め、且つ振動を抑制することが考えられる。 In order to increase the rigidity of the frame body of the saddle-type vehicle, for example, it is conceivable to use a part of the engine unit. For example, the engine unit is attached to a diamond-shaped frame body composed of a side tube and a pivot tube. At this time, the upper part of the engine is attached to the side tube of the diamond-shaped frame body by an elastic mount. In addition, the rear part of the engine unit is fixed to the pivot tube of the diamond-shaped frame body by a rigid mount.
By attaching the engine unit to the diamond-shaped frame body of the saddle-type vehicle in this way, it is conceivable to increase the rigidity of the frame body of the saddle-type vehicle and suppress vibration.
　しかし、上述のフレーム本体へのエンジンユニット取付方法においては、エンジンユニットの一部が固定されているため、未だに一部の振動が鞍乗型車両全体に伝わってしまう。
　本発明者らは、上述のようにエンジンユニットをフレーム本体に配した鞍乗型車両には、さらなるエンジンの振動がフレーム本体へ伝達されることを抑制することが望ましいことが分かった。 However, in the above-mentioned method of attaching the engine unit to the frame body, since a part of the engine unit is fixed, a part of the vibration is still transmitted to the entire saddle-type vehicle.
The present inventors have found that it is desirable to suppress further engine vibration from being transmitted to the frame body in a saddle-mounted vehicle in which the engine unit is arranged in the frame body as described above.
　本発明者らは、鞍乗型車両において、エンジンからフレーム本体に伝わる振動を抑制することについて、更に詳細に検討した。この検討の中で、本発明者らは、エンジンユニットから車両の駆動部分を分離することについて検討した。より詳細には、鞍乗型車両のエンジンユニットを、シリーズハイブリッド化することにより、発電を行う発電用エンジンと、鞍乗型車両を駆動するモータを含む駆動ユニットとに分離する。そして、発電用エンジンは、駆動ユニットとは別に、車両フレーム構造体に揺動可能に取付けられる。駆動ユニットでは、エンジンのような振動が発生しない。そのため、駆動ユニットは、車両フレーム構造体に支持されることができる。発電用エンジンでは、振動が発生する。そのため、発電用エンジンは、車両フレーム構造体に揺動可能に取付けることにより、車両フレーム構造体に伝わる振動を抑制することができる。その結果、エンジンの振動による影響を防止又は低減しつつ、駆動ユニットから駆動輪へ動力を伝達することができる。さらに、車両フレーム構造体に揺動可能に支持される発電用エンジンとは別に、駆動ユニットが車両フレーム構造体に支持されるので、駆動ユニットから駆動輪への動力伝達が、発電用エンジンの車両フレーム構造体への揺動可能な支持による影響を受けることが、防止又は抑制されることができる。その結果、駆動ユニットから駆動輪への動力伝達が効率的に行われ、車両として、入力に対する高い応答性を実現することが可能となる。 The present inventors have studied in more detail about suppressing vibration transmitted from the engine to the frame body in a saddle-mounted vehicle. In this study, the present inventors considered separating the driving part of the vehicle from the engine unit. More specifically, the engine unit of the saddle-type vehicle is separated into a power generation engine for generating power and a drive unit including a motor for driving the saddle-type vehicle by making a series hybrid. Then, the power generation engine is swingably attached to the vehicle frame structure separately from the drive unit. The drive unit does not generate vibration like an engine. Therefore, the drive unit can be supported by the vehicle frame structure. Vibration is generated in the power generation engine. Therefore, the power generation engine can be oscillatingly attached to the vehicle frame structure to suppress vibration transmitted to the vehicle frame structure. As a result, power can be transmitted from the drive unit to the drive wheels while preventing or reducing the influence of engine vibration. Further, since the drive unit is supported by the vehicle frame structure separately from the power generation engine that is swingably supported by the vehicle frame structure, the power transmission from the drive unit to the drive wheels is transmitted to the vehicle of the power generation engine. The effects of swingable support on the frame structure can be prevented or suppressed. As a result, power is efficiently transmitted from the drive unit to the drive wheels, and it becomes possible for the vehicle to realize high responsiveness to input.
　このように、発電用エンジンが車両フレーム構造体に揺動可能に支持されると共に、発電用エンジンと別に、駆動ユニットは車両フレーム構造体に支持されることにより、入力に対する高い応答性を実現しつつ、鞍乗型車両に伝わる振動を抑制することが可能となる。 In this way, the power generation engine is swingably supported by the vehicle frame structure, and the drive unit is supported by the vehicle frame structure separately from the power generation engine, thereby achieving high responsiveness to input. At the same time, it is possible to suppress the vibration transmitted to the saddle-mounted vehicle.
　以上の知見に基づいて完成した本発明の鞍乗型車両は、次の構成を備える。 The saddle-type vehicle of the present invention completed based on the above findings has the following configurations.

　発電ユニットは、発電用エンジンと、発電機とを含む。発電用エンジンは、車両フレーム構造体に揺動可能に支持される。発電用エンジンにより出力されるエンジンパワーは、機械的に駆動輪に伝達されない。そのため、駆動輪は、駆動モータから出力されたパワーによって駆動される。発電機は、可撓性を有する電力伝送媒体に接続される。発電機は、発電用エンジンから出力されたエンジンパワーを電力に変換し、変換した電力を電力伝送媒体を介して駆動モータに供給する。 The saddle-mounted vehicle of (1) includes a frame body, a drive unit, drive wheels, and a power generation unit.

The drive wheels are driven by the power output from the drive motor.
The power generation unit includes a power generation engine and a generator. The power generation engine is swingably supported by the vehicle frame structure. The engine power output by the power generation engine is not mechanically transmitted to the drive wheels. Therefore, the drive wheels are driven by the power output from the drive motor. The generator is connected to a flexible power transmission medium. The generator converts the engine power output from the power generation engine into electric power, and supplies the converted electric power to the drive motor via the power transmission medium.
　（１）の鞍乗型車両によれば、駆動輪は、駆動モータから出力されたモータパワーによって駆動される。駆動輪は、発電用エンジンから出力されたエンジンパワーが機械的に伝達されない。また、発電用エンジンがフレーム構造体に揺動可能に支持されており、発電機は可撓性を有する電力伝送媒体に接続されている。駆動ユニットは、車両フレーム構造体に揺動可能に支持される発電用エンジンとは別に、車両フレーム構造体に支持される。
これにより、（１）の鞍乗型車両は、入力に対する高い応答性を実現しつつ、鞍乗型車両に伝わる振動を抑制することが可能となる。 According to the saddle-mounted vehicle of (1), the drive wheels are driven by the motor power output from the drive motor. The engine power output from the power generation engine is not mechanically transmitted to the drive wheels. Further, the power generation engine is swingably supported by the frame structure, and the generator is connected to a flexible power transmission medium. The drive unit is supported by the vehicle frame structure separately from the power generation engine that is swingably supported by the vehicle frame structure.

　前記発電用エンジンは、前記車両フレーム構造体に車両側面視における複数箇所で、並進往復運動又は実質的に並進往復運動を行うように揺動可能に支持される一方、前記駆動ユニットは、前記発電用エンジンとは別に、前記車両フレーム構造体に弾性部材を介さずに固定される。 According to one aspect of the present invention, the saddle-mounted vehicle can adopt the following configuration.
(2) The saddle-mounted vehicle of (1)
The vehicle frame structure is composed of any one of the frame structure itself or a combination of the frame structure and the rear arm, and when the vehicle frame structure is the frame structure itself, the frame structure When the vehicle frame structure itself rotatably supports the drive wheels and the vehicle frame structure is a combination of the frame structure and the rear arm, the rear arm rotatably supports the drive wheels and the frame structure.

　（７）の鞍乗型車両によれば、鞍乗型車両のエンジンユニットを、シリーズハイブリッド化することにより、発電を行う発電用エンジンと、鞍乗型車両を駆動するモータを含む駆動ユニットとに分離できる。そして、発電用エンジンは、フレーム本体に揺動可能に取付けられる。発電用エンジンでは、振動が発生する。そのため、発電用エンジンは、鞍乗型車両のフレーム本体及び駆動ユニットの少なくとも一つに揺動可能に取付けることにより、鞍乗型車両のフレーム本体及び駆動ユニットに伝わる振動を抑制することができる。これに対し、駆動ユニットは、鞍乗型車両のリアアームに固定される。従って、（７）の鞍乗型車両によれば、鞍乗型車両の車体をコンパクトに構成できる。駆動ユニットでは、エンジンのような振動が発生しない。そのため、（７）の鞍乗型車両では、駆動ユニットをリアアームに固定したとしても、フレーム本体に振動が伝達されない。 According to the saddle-type vehicle of (7), the engine unit of the saddle-type vehicle is made into a series hybrid to form a power generation engine for generating power and a drive unit including a motor for driving the saddle-type vehicle. Can be separated. Then, the power generation engine is swingably attached to the frame body. Vibration is generated in the power generation engine. Therefore, the power generation engine can be oscillatingly attached to at least one of the frame body and the drive unit of the saddle-type vehicle to suppress the vibration transmitted to the frame body and the drive unit of the saddle-type vehicle. On the other hand, the drive unit is fixed to the rear arm of the saddle-mounted vehicle. Therefore, according to the saddle-mounted vehicle of (7), the vehicle body of the saddle-mounted vehicle can be compactly configured. The drive unit does not generate vibration like an engine. Therefore, in the saddle-mounted vehicle (7), vibration is not transmitted to the frame body even if the drive unit is fixed to the rear arm.

　（８）の鞍乗型車両によれば、フレーム本体は、前輪を回転可能に支持するフロントサスペンションを支持し、駆動輪を回転可能に支持するリアアームを揺動可能に支持する。フロントサスペンションの一例としては、フロントフォークが挙げられる。フレーム本体は、フロントフォークを回転可能に支持する。これにより、剛性の高いフレーム構造体が、前輪及び駆動輪からの荷重を受けつつ、発電用エンジンの振動が鞍乗型車両全体に伝わるのを抑制することができる。 According to the saddle-mounted vehicle of (8), the frame body supports the front suspension that rotatably supports the front wheels, and swingably supports the rear arm that rotatably supports the drive wheels. An example of a front suspension is a front fork. The frame body rotatably supports the front fork. As a result, the frame structure having high rigidity can suppress the vibration of the power generation engine from being transmitted to the entire saddle-type vehicle while receiving the load from the front wheels and the drive wheels.

The drive unit is fixed to the frame body without an elastic member.
　（９）の鞍乗型車両では、鞍乗型車両の動力源が、発電を行う発電用エンジンと、鞍乗型車両を駆動するモータを含む駆動ユニットとに分離されている。駆動ユニットでは、エンジンのような振動が発生しない。そのため、駆動ユニットは、剛性を有するメンバーとして、鞍乗型車両のフレーム本体にリジッドマウントにより固定されることができる。この場合でも、鞍乗型車両のフレーム本体及び駆動ユニットに伝わる振動を抑制することができる。 In the saddle-mounted vehicle of (9), the power source of the saddle-mounted vehicle is separated into a power generation engine for generating electricity and a drive unit including a motor for driving the saddle-mounted vehicle. The drive unit does not generate vibration like an engine. Therefore, the drive unit can be fixed to the frame body of the saddle-type vehicle by a rigid mount as a member having rigidity. Even in this case, the vibration transmitted to the frame body and the drive unit of the saddle-mounted vehicle can be suppressed.
　（９）の鞍乗型車両のように鞍乗型車両のフレーム本体に発電用エンジンと駆動ユニットとを取付けることにより、鞍乗型車両の剛性を更に高め、且つ鞍乗型車両に伝わる振動を更に抑制することが可能となる。 By attaching the power generation engine and the drive unit to the frame body of the saddle-type vehicle like the saddle-type vehicle of (9), the rigidity of the saddle-type vehicle is further increased, and the vibration transmitted to the saddle-type vehicle is suppressed.

The frame structure rotatably supports the front suspension that rotatably supports the front wheels and swingably supports the rear arm that rotatably supports the drive wheels. An example of a front suspension is a front fork. The frame body rotatably supports the front fork. As a result, the frame structure having high rigidity can suppress the vibration of the power generation engine from being transmitted to the entire saddle-type vehicle while receiving the load from the front wheels and the drive wheels.

In the following description, for purposes of illustration, a number of specific details are given to provide a complete understanding of the invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without these particular details. The present disclosure should be considered as an example of the invention and is not intended to limit the invention to the particular embodiments set forth in the drawings or description below.
　鞍乗型車両（ｓｔｒａｄｄｌｅｄ　ｖｅｈｉｃｌｅ）とは、運転者がサドルに跨って着座する形式のビークルをいう。鞍乗型車両としては、例えば、スクータ型、モペット型、オフロード型、オンロード型の自動二輪車が挙げられる。また、鞍乗型車両としては、自動二輪車に限定されず、例えば、自動三輪車、ＡＴＶ（Ａｌｌ－Ｔｅｒｒａｉｎ Ｖｅｈｉｃｌｅ）等であってもよい。自動三輪車は、２つの前輪と１つの後輪とを備えていてもよく、１つの前輪と２つの後輪とを備えていてもよい。鞍乗型車両の駆動輪は、後輪であってもよく、前輪であってもよい。また、鞍乗型車両の駆動輪は、後輪及び前輪の双方であってもよい。駆動輪は、発電用エンジン又は駆動モータから出力される機械的なパワーのうち、駆動モータから出力される機械的パワーのみによって駆動される。このような鞍乗型車両は、シリーズハイブリッド式鞍乗型車両である。 A saddle-type vehicle (stradled vehicle) is a vehicle in which the driver sits across the saddle. Examples of the saddle-mounted vehicle include a scooter type, a moped type, an off-road type, and an on-road type motorcycle. Further, the saddle-mounted vehicle is not limited to a motorcycle, and may be, for example, a motorcycle, an ATV (All-Terrain Vehicle), or the like. A tricycle may have two front wheels and one rear wheel, or may have one front wheel and two rear wheels. The drive wheels of the saddle-mounted vehicle may be rear wheels or front wheels. Further, the drive wheels of the saddle-mounted vehicle may be both rear wheels and front wheels. The drive wheels are driven only by the mechanical power output from the drive motor among the mechanical power output from the power generation engine or the drive motor. Such a saddle-mounted vehicle is a series hybrid saddle-mounted vehicle.
　また、鞍乗型車両は、リーン姿勢で旋回可能に構成されていることが好ましい。リーン姿勢で旋回可能に構成された鞍乗型車両は、カーブの内側に傾いた姿勢で旋回するように構成される。これにより、リーン姿勢で旋回可能に構成された鞍乗型車両は、旋回時に鞍乗型車両に加わる遠心力に対抗する。リーン姿勢で旋回可能に構成された鞍乗型車両としては、例えば、自動二輪車及び自動三輪車が挙げられる。リーン姿勢で旋回可能に構成された鞍乗型車両では、軽快性が求められるため、発進の操作に対する進行の応答性が重要視される。 Further, it is preferable that the saddle-mounted vehicle is configured to be able to turn in a lean posture. A saddle-mounted vehicle configured to be able to turn in a lean posture is configured to turn in a posture tilted inward of a curve. As a result, the saddle-mounted vehicle configured to be able to turn in a lean posture opposes the centrifugal force applied to the saddle-mounted vehicle during turning. Examples of the saddle-mounted vehicle configured to be able to turn in a lean posture include a motorcycle and a motorcycle. In a saddle-mounted vehicle that is configured to be able to turn in a lean posture, lightness is required, so the responsiveness of progress to the starting operation is important.
　フレーム本体は、鞍乗型車両の骨格をなし、エンジン、発電ユニット、駆動ユニット、バッテリ、及び燃料タンク等の鞍乗型車両の搭載部品等を支持する。フレーム本体は、ヘッドパイプと、ヘッドパイプに固定された桁部とから構成される。フレーム本体は、ヘッドパイプ及び桁部と、それ以外の部品とにより構成されていてもよく、また、ヘッドパイプ及び桁部以外の部品により構成されていてもよい。桁部は、単一のパイプから構成されてもよく、また、複数のパイプの組み合わせで構成されてもよい。また、桁部は、板等のパイプ以外の構造物により構成されてもよい。フレーム本体は、例えば、シングルグレードル型、ダブルグレードル型、ダイヤモンド型、及びモノコック型等が挙げられるが、これらに限定されない。
　フレーム構造体は、車両フレーム構造体を構成する。車両フレーム構造体は、前輪及び後輪からの荷重を受ける構造体である。鞍乗型車両がリアアームを備える場合、車両フレーム構造体は、フレーム構造体とリアアームとからなる。鞍乗型車両がリアアームを備えない場合、車両フレーム構造体は、フレーム構造体自体である。即ち、車両フレーム構造体は、フレーム構造体そのもの、又はフレーム構造体とリアアームとの組合せ、のいずれかである。なお、フレーム構造体は、フレーム本体以外の部品を有してもよい。例えば、フレーム本体及びフレーム本体にリジッドに固定された駆動ユニットがフレーム構造体を構成してもよい。駆動ユニットは、これに限られず例えば、フレーム構造体を構成しなくともよい。この場合、駆動ユニットは、前輪及び後輪からの荷重を受ける構造体として機能しない。 The frame body forms the skeleton of a saddle-type vehicle, and supports mounting parts of the saddle-type vehicle such as an engine, a power generation unit, a drive unit, a battery, and a fuel tank. The frame body is composed of a head pipe and a girder portion fixed to the head pipe. The frame body may be composed of a head pipe, a girder portion, and other parts, or may be composed of parts other than the head pipe and the girder portion. The girder portion may be composed of a single pipe, or may be composed of a combination of a plurality of pipes. Further, the girder portion may be composed of a structure other than a pipe such as a plate. Examples of the frame body include, but are not limited to, a single gradel type, a double gradel type, a diamond type, and a monocoque type.
The frame structure constitutes the vehicle frame structure. The vehicle frame structure is a structure that receives loads from the front wheels and the rear wheels. When a saddle-mounted vehicle includes a rear arm, the vehicle frame structure includes a frame structure and a rear arm. If the saddle-mounted vehicle does not have a rear arm, the vehicle frame structure is the frame structure itself. That is, the vehicle frame structure is either the frame structure itself or a combination of the frame structure and the rear arm. The frame structure may have parts other than the frame body. For example, the frame body and a drive unit rigidly fixed to the frame body may form the frame structure. The drive unit is not limited to this, and for example, the frame structure may not be formed. In this case, the drive unit does not function as a structure that receives loads from the front and rear wheels.

The generator may function as a starting motor. However, the generator may be a rotary electric machine different from the starting motor. The generator may be an outer rotor type or an inner rotor type. Further, the generator may be an axial gap type instead of the radial gap type. According to one embodiment, in the generator, the rotor comprises a permanent magnet.
　発電機が、発電用エンジンで駆動される構成とは、例えば、発電用エンジンのクランク軸と連動するよう設けられ、発電機の被駆動軸が、固定された速度比で回転するよう動力伝達機構を介して発電用エンジンのクランク軸に接続されることである。また、発電機が、動力伝達機構を介さずに発電用エンジンのクランク軸と直結されていてもよい。 The configuration in which the generator is driven by the power generation engine is, for example, a power transmission mechanism provided so as to interlock with the crankshaft of the power generation engine so that the driven shaft of the generator rotates at a fixed speed ratio. It is connected to the crankshaft of the power generation engine via. Further, the generator may be directly connected to the crankshaft of the power generation engine without using a power transmission mechanism.
　駆動モータは、モータ動作が可能な回転電機である。駆動モータは、例えば発電とモータ動作の双方が可能な回転電機であってもよい。駆動モータは、アウターロータ型でもよく、また、インナーロータ型でもよい。また、駆動モータは、ラジアルギャップ型でなく、アキシャルギャップ型でもよい。一つの実施形態によれば、駆動モータでは、ロータが、永久磁石を備えている。 The drive motor is a rotary electric machine that can operate the motor. The drive motor may be, for example, a rotary electric machine capable of both power generation and motor operation. The drive motor may be an outer rotor type or an inner rotor type. Further, the drive motor may be an axial gap type instead of the radial gap type. According to one embodiment, in the drive motor, the rotor comprises a permanent magnet.

Examples of the power transmission medium include electric wires and cables. However, the flexible power transmission medium may be a combination of a flexible member and a rigid body. For example, the flexible power transmission medium may be a combination of an electric wire and a circuit board.
　支持するとは、支持する部品が支持される部品の荷重を直接的又は間接的に受けることをいう。支持されるとは、支持される部品が支持する部品に直接的又は間接的に荷重をかけることをいう。ここで直接的は、支持する部品が支持される部品と接触して荷重を受けることを意味する。また、間接的は、支持する部品が支持される部品と接触せずに他の部品を介して荷重を受けることを意味する。支持する部品と支持される部品の接点は、例えば、固定されていてもよい。支持する部品と支持される部品は、例えば、揺動可能に接続されていてもよい。また、支持する部品と支持される部品は、例えば、回転可能に接続されていてもよい。支持する部品と支持される部品の接続部分は、直接部品同士が接続されていてもよい。支持する部品と支持される部品の接続部分は、例えば弾性部材、ベアリング等を介して部品同士が接続されていてもよい。 Supporting means that the supporting part receives the load of the supported part directly or indirectly. Being supported means that the supported parts directly or indirectly apply a load to the supported parts. Directly here, it means that the supporting part comes into contact with the supported part and receives a load. Indirectly, it also means that the supporting component receives a load through another component without contacting the supported component. The contact points between the supporting component and the supported component may be fixed, for example. The supporting component and the supported component may be oscillatingly connected, for example. Further, the supporting component and the supported component may be rotatably connected, for example. The connecting portion between the supporting component and the supported component may be directly connected to each other. The connecting portion between the supporting component and the supported component may be connected to each other via, for example, an elastic member or a bearing.
　リジッドに固定されるとは、弾性部材又は緩衝部材等からなる可動部分を介することなく、支持される部品が支持する部品と直接的に又は間接的に固定されることである。支持される部品は、例えば、支持する部品と固定される。 Rigid fixing means that the supported part is directly or indirectly fixed to the supported part without the intervention of a movable part made of an elastic member, a cushioning member, or the like. The supported component is fixed, for example, to the supporting component.

　リンク部材１１４は、ベアリング４７１に支持された取付軸４６１及びベアリング４７２に支持された取付軸４６２から鞍乗型車両１の左右方向ＬＲに伸びる直線を中心軸として回転する。リンク部材５３６は、ベアリング４７３に支持された取付軸４６３から鞍乗型車両１の左右方向ＬＲに伸びる直線を中心軸として回転する。リンク部材５３７は、ベアリング４７４に支持された取付軸４６４から鞍乗型車両１の左右方向ＬＲに伸びる直線を中心軸として回転する。また、リンク部材１１４は、弾性部材４４１及び４４２を介して発電用エンジン４１に取付けられる。リンク部材５３６及び５３７は、それぞれ弾性部材４４３及び４４４を介して発電用エンジン４１に取付けられる。従って、発電用エンジン４１は、重心Ｇから鞍乗型車両１の左右方向ＬＲに伸びる直線を中心軸として回転する。これにより、鞍乗型車両１の発電用エンジン４１は、鞍乗型車両１の上下方向ＵＤ及び前後方向ＦＢにおける振動がフレーム構造体１０に伝達することを抑制することができる。また、発電用エンジン４１は、バランサ４１６により、発電用エンジン４１の一次慣性力を抑制する。従って、本実施形態の鞍乗型車両１は、リンク部材１１４、５３６及び５３７と、バランサ４１６とを組み合わせることにより、効率的に発電用エンジン４１の振動が車両フレーム構造体１０に伝達されるのを抑制することができる。 The link member 114 rotates about a straight line extending in the left-right direction LR of the saddle-mounted vehicle 1 from the mounting shaft 461 supported by the bearing 471 and the mounting shaft 462 supported by the bearing 472 as the central axis.

The link member 537 rotates about a straight line extending from the mounting shaft 464 supported by the bearing 474 in the left-right direction LR of the saddle-mounted vehicle 1 as a central axis. Further, the link member 114 is attached to the power generation engine 41 via the elastic members 441 and 442. The link members 536 and 537 are attached to the power generation engine 41 via the elastic members 443 and 444, respectively. Therefore, the power generation engine 41 rotates about a straight line extending from the center of gravity G in the left-right direction LR of the saddle-mounted vehicle 1. As a result, the power generation engine 41 of the saddle-mounted vehicle 1 can suppress the transmission of vibrations in the vertical direction UD and the front-rear direction FB of the saddle-mounted vehicle 1 to the frame structure 10. Further, the power generation engine 41 suppresses the primary inertial force of the power generation engine 41 by the balancer 416. Therefore, in the saddle-mounted vehicle 1 of the present embodiment, the vibration of the power generation engine 41 is efficiently transmitted to the vehicle frame structure 10 by combining the link members 114, 536 and 537 and the balancer 416. Can be suppressed.
　リンク部材１１４は、弾性部材４４５及び４４６を介してフレーム本体１１０に取付けられる。リンク部材５３６は、弾性部材４４７を介してギアボックス５３に取付けられる。これにより、鞍乗型車両１の発電用エンジン４１は、弾性部材４４５～４４７が過度の揺動を抑制するストッパとなり、鞍乗型車両１の上下方向ＵＤ及び前後方向ＦＢに大きく揺動することを抑制することができる。 The link member 114 is attached to the frame body 110 via the elastic members 445 and 446. The link member 536 is attached to the gearbox 53 via the elastic member 447. As a result, in the power generation engine 41 of the saddle-type vehicle 1, the elastic members 445 to 447 serve as stoppers for suppressing excessive rocking, and the saddle-type vehicle 1 swings significantly in the vertical direction UD and the front-rear direction FB. Can be suppressed.
　ギアボックス５３は、前方向及び後方向を含む鞍乗型車両１の前後方向ＦＢにおいて、フレーム本体１１０の後端部に、４点でリジッドに固定される。詳細には、図７乃至図９のギアボックス５３の取付部５６１から５６４の４点において、フレーム本体１１０が、ゴムブッシュ等の弾性部材を介することなく、ギアボックス５３と接触して固定される。ここで、取付部５６１は、ギアボックス５３の左上部に設けられ、取付部５６２は、ギアボックス５３の左下部に設けられる。また、取付部５６３は、ギアボックス５３の右上部に設けられ、取付部５６４は、ギアボックス５３の右下部に設けられる。支持方法は、例えばギアボックス５３の取付部５６１から５６４において、フレーム本体１１０をボルトで固定する。 The gearbox 53 is rigidly fixed to the rear end of the frame body 110 at four points in the front-rear direction FB of the saddle-mounted vehicle 1 including the front direction and the rear direction. Specifically, the frame main body 110 is fixed in contact with the gearbox 53 at four points of the mounting portions 561 to 564 of the gearbox 53 of FIGS. 7 to 9 without the need for an elastic member such as a rubber bush. .. Here, the mounting portion 561 is provided at the upper left portion of the gearbox 53, and the mounting portion 562 is provided at the lower left portion of the gearbox 53. Further, the mounting portion 563 is provided in the upper right portion of the gearbox 53, and the mounting portion 564 is provided in the lower right portion of the gearbox 53. As a support method, for example, the frame body 110 is fixed with bolts at the mounting portions 561 to 564 of the gearbox 53.
　ギアボックス５３は、フレーム本体１１０にリジッドに固定されるため、フレーム本体１１０と一体となってフレーム構造体１１を構成する。これにより、ギアボックス５３は、フレーム本体１１０とともに、鞍乗型車両１の骨格を形成し、前輪２２、後輪３２、及び発電ユニット４０からの荷重を受けることができる。 Since the gearbox 53 is rigidly fixed to the frame body 110, it constitutes the frame structure 11 integrally with the frame body 110. As a result, the gearbox 53, together with the frame body 110, forms the skeleton of the saddle-mounted vehicle 1 and can receive the loads from the front wheels 22, the rear wheels 32, and the power generation unit 40.
　鞍乗型車両１では、駆動ユニット５０のギアボックス５３が、フレーム本体１１０に弾性部材を介することなくリジッドに固定されることによりフレーム構造体１１を構成する。これにより、鞍乗型車両１は、ギアボックス５３をフレーム構造体１１の剛性メンバーとして使用でき、鞍乗型車両の剛性を高めることができる。
　また、鞍乗型車両１では、駆動輪である後輪３２が、駆動モータ５１から出力されたパワーのみによって駆動され、発電用エンジン４１から出力されたパワーが伝達されない。これに対し、発電用エンジン４１は、フレーム本体１１０に揺動可能に支持されており、発電ユニットの発電機４２と駆動モータ５１とは、可撓性を有し振動を伝達しない電力伝送媒体により接続されている。従って、鞍乗型車両１は、フレーム構造体１１の剛性を高めつつ、発電用エンジン４１の振動が、フレーム本体１１０及び駆動ユニット５０を含むフレーム構造体１１を介して鞍乗型車両全体に伝わることを抑制することができる。 In the saddle-mounted vehicle 1, the gearbox 53 of the drive unit 50 is rigidly fixed to the frame body 110 without an elastic member, thereby forming the frame structure 11. As a result, the saddle-mounted vehicle 1 can use the gearbox 53 as a rigid member of the frame structure 11, and can increase the rigidity of the saddle-mounted vehicle.
Further, in the saddle-mounted vehicle 1, the rear wheels 32, which are the driving wheels, are driven only by the power output from the drive motor 51, and the power output from the power generation engine 41 is not transmitted. On the other hand, the power generation engine 41 is swingably supported by the frame body 110, and the generator 42 and the drive motor 51 of the power generation unit are made of a power transmission medium that is flexible and does not transmit vibration. It is connected. Therefore, in the saddle-type vehicle 1, the vibration of the power generation engine 41 is transmitted to the entire saddle-type vehicle via the frame structure 11 including the frame body 110 and the drive unit 50 while increasing the rigidity of the frame structure 11. Can be suppressed.
　図７乃至図９のギアボックス５３に設けられた取付部５７１及び５７２の２点において、リアアーム３１が、ギアボックス５３に揺動可能に支持される。ここで、取付部５７１は、ギアボックス５３の左部に設けられ、取付部５７２は、ギアボックス５３の右部に設けられる。詳細には、動力伝達機構５３１の出力軸５３４が取付部５７１及びリアアーム３１を貫通している。また、取付ボルト５７３（図８参照）が、リアアーム３１を貫通し、ギアボックスの取付部５７２に設けられた取付穴に挿入される。 The rear arm 31 is swingably supported by the gearbox 53 at two points of mounting portions 571 and 572 provided in the gearbox 53 of FIGS. 7 to 9. Here, the mounting portion 571 is provided on the left portion of the gearbox 53, and the mounting portion 572 is provided on the right portion of the gearbox 53. Specifically, the output shaft 534 of the power transmission mechanism 531 penetrates the mounting portion 571 and the rear arm 31. Further, the mounting bolt 573 (see FIG. 8) penetrates the rear arm 31 and is inserted into the mounting hole provided in the mounting portion 572 of the gearbox.

Further, the link members 2114 to 2116 are attached to the power generation engine 241 via the elastic members 2441 to 2444, respectively. Therefore, the power generation engine 241 of the saddle-type vehicle 200 can suppress the transmission of vibrations in the vertical direction UD and the front-rear direction FB of the saddle-type vehicle 200 to the frame structure 211 (that is, the frame body 2110). .. Further, the power generation engine 241 suppresses the primary inertial force of the power generation engine 241 by providing a balancer. Therefore, the saddle-mounted vehicle 200 of the present embodiment efficiently transmits the vibration of the power generation engine 241 to the frame structure 211 by combining the link members 2114 to 2116 and the balancer of the power generation engine. Can be suppressed.

The link member 2115 is attached to the frame body 2110 via the elastic member 2447. As a result, in the power generation engine 241 of the saddle-type vehicle 200, the elastic members 2445 to 2447 serve as a stopper for suppressing excessive rocking, and the saddle-type vehicle 200 swings significantly in the vertical direction UD and the front-rear direction FB. Can be suppressed.
　本実施形態において、コントロールユニット２５２は、駆動ユニット２５０に含まれてもよいし、含まれなくてもよい。即ち、本実施形態において、コントロールユニット２５２は、駆動ユニット２５０と一体となってリアアーム２３１を構成してもよいし、鞍乗型車両１のフレーム本体２１１０に取付けられてもよい。 In the present embodiment, the control unit 252 may or may not be included in the drive unit 250. That is, in the present embodiment, the control unit 252 may be integrated with the drive unit 250 to form the rear arm 231 or may be attached to the frame body 2110 of the saddle-mounted vehicle 1.
　（変形例）
　駆動ユニット２５０は、ギアボックス２５３を含まないように構成できる。本実施形態の変形例において、駆動モータ２５１は、リアアーム２３１に取付けられ、駆動モータ２５１の出力軸に後輪２３２の中心軸が直接に接続される。即ち、駆動モータ２５１は、後輪２３２のインホイールモータとして構成される。 (Modification example)
The drive unit 250 can be configured not to include the gearbox 253. In the modified example of the present embodiment, the drive motor 251 is attached to the rear arm 231 and the central shaft of the rear wheel 232 is directly connected to the output shaft of the drive motor 251. That is, the drive motor 251 is configured as an in-wheel motor of the rear wheel 232.
